GE- FREQUENCY APPARATUS.

Specification of Letters Iatent.

Patented Sept. 2 1911.

Application filed November 21, 1910. Serial No. 593,364.

To all whom it may concern:

Be it known that I, WILLIAM DUBILIER, in the county of King, and in the State of Washington have invented a certain new and useful mprovement in High,- Frequency Apparatus, and do hereby declare that the following is a full, clear, and

' exact description thereof. 1

ends my invention The object of my invention has been to provide an ap aratus for producing high frequency oscil ations'which shall have the advantages of transforming a high percentage of the primary current into such oscillations, and of maintaining its efficient operation with unusual reliability; and to such consists in the apparatus for producing high frequency oscillations hereinafter specified.

In the accompanying drawings, Figure 1 is a diagrammatic view of an apparatus embodying my invention; Figs. 2 and 3 are respectively a side elevation and a central longitudinal section of electrodes used in such ap aratus.

. My apparatus relates to the type, in which a primary current, either alternating or diroot, is transformed at a s ark or are gap into high frequency oscillations. In the acfrom the generator 10,

which. may be either DCorAC,toa1ine wire 11, and thence the current passes through a choke coil 12 to an electrode 13. From the said electrode it asses across the gap to an electrode 14, and thence by wire 15 through a choke coil 16 and back to the generator by a wire 17. The electrodes consist of an inner electrode 18, of circular cross-section, and an outer electrode 19, also of circulancross-section, the said electrodes being concentric, and having a space between them, across which space the current flows.

It is obvious that many changes can be made in the above described embodiment of my invention which will be within the scope of the invention, and such embodiment is to be regarded as only typical.

I claim In an apparatus for producing electric oscillations, the combination of electrodes circular in cross-section, one of them being annular and the other substantially cylindrical and within the annular one, said electrodes being co-axial, and means for rotating said electrodes relatively to each other.

In testimony that I claim the foregoing I have hereunto set my hand.

WILLIAM DUBILIER.
